Women in power-themed tasks: Need for power predicts task enjoyment and power stress

The implicit power motive predicts individuals’ involvement in activities that allow them to have impact and influence on other people. Moreover, substantial evidence indicates that thwarting individuals’ implicit power motive relates to so-called power stress. The present series of studies addresses both topics among female participants. In study 1, findings indicate that the strength of the implicit power motive moderates the relationship between women’s self-reported dominance and their evaluations of a power-related task: A significant link between self-reported dominance and both motivation for task participation and task enjoyment could be verified only when the implicit power motive was well-pronounced. In the subsequent studies, actual and anticipated thwarting of the satisfaction of a strong implicit power motive was associated with different psychological and behavioral indicators of power stress. Participants with a high implicit power motive felt more negative affect (study 2), reported more negative explicit (study 3) and implicit (study 4) attitudes towards a dominant target person, and were coded more often for visible frown reactions (study 5) when the satisfaction of their implicit power motive was (potentially) thwarted compared to participants with a low implicit power motive and participants with a high implicit power motive that was, however, not at risk of being thwarted.

     

‘It was all intertwined’: Illness representations and self-management in patients with cancer and anxiety/depression

Objective: Cancer and anxiety/depression frequently co-occur, leading to poorer outcomes for these illnesses. However, the majority of existing research investigates how participants view single illnesses alone. This study aimed to explore the content of individuals’ multimorbid representations and how these relate to their coping behaviours and self-management strategies for cancer and anxiety/depression.

Design: A semi-structured qualitative research design with theoretical thematic analysis.

Main Outcome Measures: Multimorbid illness representations, coping behaviours, and self-management strategies.

Results: In interviews with 21 participants multimorbid representations varied, three participants viewed cancer and anxiety/depression as unrelated, five participants were uncertain about the relationship between cancer and anxiety/depression, and the majority of participants perceived cancer and anxiety/depression as related. This third group of participants often described relationships as causal, with representations having both positive and negative influences on coping behaviours and self-management strategies. Representations were shown to change over the course of the cancer experience, with fear of cancer recurrence and the influence of participants’ most challenging illness also discussed.

Conclusions: People hold multimorbid illness representations that can influence self-management. An awareness of these representations by researchers, health professionals, and patients is important for the creation of future interventions that aim to improve and maintain patient wellbeing.     

Posture based motor planning in a sequential grasping task

Movement planning in sequential tasks is revealed by grasping postures. We explored aspects of planning a sequential drawer opening and object manipulation task with regard to arm and torso postures. We conducted a detailed kinematic analysis of joint postures at the wrist, elbow, and shoulder for a one-grasp and a two-grasp sequence of movement. The second of the two-grasp sequence was constrained (uncomfortable). We predicted that planning for the second grasp in a two-grasp sequence would influence arm, torso, and whole-body postures at the first grasp. Participants prepared for the second grasp by adjusting the posture of the elbow and shoulder and the distance they stepped to the drawer. The joint postures at the elbow and shoulder changed in the direction of the intended object grasp. These findings show that anticipatory adjustments are revealed at postures other than the end-effector and lend insight into the mechanisms of sequential movement planning.     

Self‐regulation and well‐being: The influence of identity and motives

The relationship between self‐regulatory capacities and self‐esteem as well as well‐being is examined by a mediation model that views self‐regulation as promoting the development of identity achievement which, in turn, is expected to be associated with well‐being. Among secondary school students (Study 1) identity achievement mediated the association between the self‐regulatory capacity of attention control and self‐esteem. In Study 2 (university students), the mediational effect of identity achievement was found for the relationship between the self‐regulatory capacity of action control and well‐being. Explicit motives moderated this association. In sum, a firm identity enhances well‐being by lending a sense of continuity to one's life. However, explicit motives have a substitution effect by giving direction to life when lacking firm identity commitments. Copyright © 2010 John Wiley & Sons, Ltd.     

Phonological abstraction in processing lexical-tone variation: evidence from a learning paradigm

There is a growing consensus that the mental lexicon contains both abstract and word-specific acoustic information. To investigate their relative importance for word recognition, we tested to what extent perceptual learning is word specific or generalizable to other words. In an exposure phase, participants were divided into two groups; each group was semantically biased to interpret an ambiguous Mandarin tone contour as either tone1 or tone2. In a subsequent test phase, the perception of ambiguous contours was dependent on the exposure phase: Participants who heard ambiguous contours as tone1 during exposure were more likely to perceive ambiguous contours as tone1 than participants who heard ambiguous contours as tone2 during exposure. This learning effect was only slightly larger for previously encountered than for not previously encountered words. The results speak for an architecture with prelexical analysis of phonological categories to achieve both lexical access and episodic storage of exemplars.     

Signal detection and threshold models of source memory

Recently, several authors claimed that the curvilinear shape of rating-based source memory receiver operating characteristics (ROCs) refutes threshold models. However, rating-based ROCs are not diagnostic to disprove threshold models. Furthermore, source memory ROC-analyses ignore influences of other processes like old-new-detection and old-new-response-tendencies, so direct estimation of parameters is preferable. Five source monitoring experiments with different response bias manipulations and materials were conducted. We fitted the Two High Threshold Multinomial Model of Source Monitoring by Bayen, Murnane, and Erdfelder (1996) and the Multivariate Signal Detection Model for Selection DeCarlo (2003). We also included rating-based ROCs. The results suggest that both models are at least equally valid as measurement tools which capture bias processes in the corresponding parameters, and they can perhaps be integrated theoretically.
